Confused - HTTP request size limit of 100 MB for Azure Function

Question

Hi Team,

I'm really confused from Microsoft documentations regarding HTTP request size limitation for HTTP triggered Azure Function:

1. This documentation says - Max limit is 100 MB : https://learn.microsoft.com/en-us/azure/azure-functions/functions-bindings-http-webhook-trigger?tabs=python-v2%2Cisolated-process%2Cnodejs-v4%2Cfunctionsv2&pivots=programming-language-csharp#limits
2. This documentation says it can be changed to any size beyond 100 MB: https://learn.microsoft.com/en-us/azure/azure-functions/functions-app-settings#functions_request_body_size_limit

Can anyone please help me with correct answer as one of my colleague claimed he send 300 MB HTTP request body to Azure function and it worked well.

Is there any difference between implementation of Azure functions like : OS Linux, Language Java or OS Windows Language .Net etc?

Please help.

Regards,

Partha

Answer 1

The default limit is 100 MB, but it can be increased by configuring the Functions_Request_Body_Size_Limit app setting.

There is no differences in the HTTP request size limitations based on the operating system or programming language.

Exceeding the limit is generally not recommended due to performance and memory issues. Consider using Azure Blob Storage or chunking for large data.
